I just bought this old air compressor

I just bought this air compressor and don't know what some of these things are coming off of it.

Wanted to find out how to hook this air compressor up so it's safe to use but I can't identify what the lines are coming off the top and the side any help would be greatly appreciated.

The only markings I can find on it worth a 101 or it could be a 707, on the pulley wheel it says k134n and it's a text to A Leland motor that's very old but I don't know if that was originally with it or not
